In order to welcome the transportation during the Qingming holiday and ensure the good air quality of the train carriage, the Zhengzhou depot of China Railway Zhengzhou Bureau Group Co., Ltd. carried out the action of “clearing the lungs” of passenger cars, and organized professionals to clean and disinfect the air conditioning filter screen and ventilation system of the train, so as to comprehensively improve the riding experience of passengers.

It is understood that after each air-conditioned passenger train enters the passenger station, the inspector needs to operate on the 4.4-meter-high roof, disassemble and inspect hundreds of parts such as screws, gaskets and spring pads in the key parts of each vehicle, clean the air-conditioning filter screen of the train with a high-pressure water gun, replace the air-conditioning filter screen with many floating flocs, and spray disinfectant to ensure the safety and hygiene of the air-conditioning system of the train.
